Hyman should be a super-elite 4th liner. But Babs has chained him to Matthews. He is a great PKer, strong on the forecheck, and excellent at puck recovery in the offensive zone. But he should not be a fixture next to our best player. However that is on the coach, not Hyman. His deal is pretty reasonable for what he brings.
For the faceoffs, I will point out that they did not change the rule. They are simply enforcing it. But everyone cheats a ton anyways, so I'm not sure where this is going to get them. And I doubt it continue much once the season starts.
